This product is a combination of the alloy ankle processed by high-precision calculators and the carbon fiber foot plate produced by the cutting-edge technology carbon fiber molding process. The design structure of the special carbon plate multi-plate linkage structure allows the vibration absorption ability to be stronger during walking, which is derived from the resistance of different ground responses, and is closer to the normal human ankle joint when walking. The foot plate made of light and high strength carbon fiber composite material has high comfort stability and is more flexible and light.
